Ink Droplet Position Compensation Based on Extended State Observer
International Journal of Automation Technology, 2010 The parabolic droplet trajectory in inkjet printing causes errors between actual position and expected positioning, deteriorating printing quality in highspeed printing. To improve printing quality and increase printing speed, an accurate firing time estimation method is proposed to compensate the droplet position error.
